Or, more precisely, as a "char *" (4.2BSD) or a "char **" (4.3BSD).  The
code in the 4.3BSD <netdb.h> is:

	char	**h_addr_list;	/* list of addresses from name server */
#define	h_addr	h_addr_list[0]	/* address, for backward compatiblity */

SunOS 4.0 has the 4.3BSD-style <netdb.h> (regardless of whether you use
-lresolv to go directly to BIND, or use the standard -lc "gethost*" to
go through "/etc/hosts" and YP and get to BIND through the YP server).
